Twigy Feng is a competitive freediver, AIDA-certified safety diver, and Molchanovs Wave 2 instructor based in Orlando, Florida. She has served as in-water safety and rescue for depth and pool competitions across multiple countries — including Costa Rica's AIDA Champion Cup, the Nicaragua Apoyo Competition, and the first-ever ice diving event held in the United States — and currently ranks #5 among female depth athletes in the USA.

Off the line, she serves as an ambassador for The Only One, a marine conservation NGO, promoting sustainable ocean practices alongside her competition work. Mazu Freediving carries that same dual commitment: building strong, safe divers while protecting the ocean they train in.

Why "Mazu"

In Chinese coastal tradition, Mazu is the sea goddess who calms storms and guides sailors safely home. It's a fitting namesake: staying calm under pressure and guiding people safely through deep water is exactly the work Twigy has built her career around — as an athlete, an instructor, and a safety diver standing by at the world's most demanding competitions.

Testimonials

"

My freediving has accelerated significantly in a short amount of time. Throughout my journey, crisp technique has been a top goal, and Twigy has strongly guided me in this area. From finning and arm pulls to no-fin kick cycles, I've seen consistent improvement in my form and technique through her video review and feedback, assessment of my time, distance, and depth results, and in-person coaching. She's patient and understanding, and she knows how to pivot her approach to ensure the teaching resonates.
